Implementation of mechanistic-empirical pavement analysis in the State of Qatar
(
Taylor & Francis
, 2014 , Article)
The State of Qatar is experiencing tremendous growth in infrastructure including road network and highways. The current methods used in design of asphalt pavements in the State of Qatar are empirical and might not be ...
Rheological evaluation of shortand long-term performance for warm mix asphalt (WMA) binders
(
Kluwer Academic Publishers
, 2016 , Article)
Warm-mix asphalt (WMA) additives are environmentally friendly and cost-effective products that lower the viscosity of bituminous binders to allow reduction of mixing and compaction temperatures in asphalt mix production. ...
Effect of ageing on asphalt binders in the State of Qatar: a case study
(
Taylor and Francis Ltd.
, 2017 , Article)
Ageing of asphalt binders has a significant impact on the rheological properties of asphalt binders and thus affects the performance of asphalt pavements. The rate of binder ageing is accelerated at high temperatures. This ...
State-of-the-Art Review on Sustainable Design and Construction of Quieter Pavements-Part 2: Factors Affecting Tire-Pavement Noise and Prediction Models
(
MDPI AG
, 2016 , Article Review)
Traffic noise is a combination of noises produced from a number of sources. Of all the traffic noise sources, tire-pavement noise, which is emitted as a result of the interaction of rolling,slipping, or dragging tires and ...
Demonstrating the Worth of Recycled Aggregates - A Case Study from Qatar
(
American Society of Civil Engineers (ASCE)
, 2016 , Conference Paper)
Recycled aggregates are widely used in unbound applications in many countries. However, in some areas the materials available may not meet all the requirements of the local specifications. This is the case in Qatar, where ...
Probabilistic analysis of fatigue life for asphalt mixtures using the viscoelastic continuum damage approach
(
Elsevier Ltd
, 2016 , Article)
Fatigue cracking is one of the most serious distress modes affecting the serviceability of asphalt pavement structures. The inherent variability of asphaltic materials exhibited in fatigue test results, especially for ...
Comparative evaluation of fatigue resistance of warm fine aggregate asphalt mixtures
(
Elsevier Ltd
, 2016 , Article)
Fatigue cracking is one of the crucial distresses in asphalt pavements that affect its service life and rehabilitation process. The resistance of asphalt mixtures to fatigue failure in the laboratory experiments is influenced ...
Evaluation of Federal Highway Administration’s Traffic Noise Model for Pavements in Qatar
(
Springer Nature
, 2020 , Book chapter)
Traffic noise is an irritating problem especially for residents near major transportation corridors. It’s in the interest of transportation agencies to check the noise level to develop measures to reduce noise if it exceeds ...
Nanoscale evaluation of multi-walled carbon nanotube’s performance on resisting oxidization of asphalt
(
Trans Tech Publications Ltd
, 2019 , Conference Paper)
Nanotechnology has contributed significantly to different subfields of the construction industry, including asphalt pavement engineering. The improved properties and new functionalities of the nanomaterials have provided ...
Characterisation of air voids in w-fam samples using x-ray ct imaging
(
CRC Press/Balkema
, 2018 , Conference Paper)
This study documents the use of high-resolution X-Ray Computed Tomography to characterise air void distribution in Fine Aggregate Mixtures (FAM) prepared using Warm Mix Asphalt (WMA) additives (W-FAM). Specimens were imaged ...
